Silencers
Aras Power Systems provides engineered exhaust and inlet silencers for gas turbines, engines, fans and industrial process systems, reducing near-field and far-field noise without compromising pressure drop or plant performance. Silencer systems are customised for acoustic duty, flow rate, temperature, allowable pressure loss, space constraints and site noise limits.
Codes & standards
Aras Power Systems designs exhaust and inlet silencers to the client-nominated code basis, combining international standards with project-specific operating, safety and documentation requirements.
- ASME
- EN standards
- ISO 9613 / acoustic modelling
- ASME IX
- ISO 12944
Our Services
Our engineering and supply scope is structured to deliver safe, efficient and project-specific equipment from concept design through fabrication, site support and documentation.
Design compliance
- International standards: aligning silencer design with applicable ASME, EN, acoustic and fabrication requirements.
- Custom acoustic engineering: tailoring baffle geometry, casing, splitter arrangement and lining materials to the required insertion loss.
Computational Fluid Dynamics (CFD)
- Flow optimisation: reviewing velocity distribution and pressure drop through silencer baffles.
- Acoustic performance support: integrating flow behaviour with acoustic design to avoid excessive turbulence and self-generated noise.
Finite Element Analysis (FEA)
- Structural assessment: checking casing, baffles, supports and connections under operating and extreme load cases.
- Material suitability: selecting materials for high-temperature, vibration and corrosive environments.
Elevated-temperature design
- High-temperature operation: engineering exhaust silencers for gas turbine and engine exhaust conditions.
- Thermal stress analysis: incorporating expansion allowances and support details for durable operation.
Sound attenuation optimisation
- Acoustic modelling: developing attenuation solutions for octave-band noise requirements.
- Regulatory compliance: supporting site noise limits and environmental noise-control targets.
Documentation and quality assurance
- Performance data: providing acoustic, pressure-drop and mechanical design information.
- Installation guidance: issuing drawings, lifting details, inspection plans and maintenance guidance.

Frequently asked questions
Can silencers be designed for a specific noise limit?
Yes. Silencers are engineered according to octave-band noise data, required insertion loss and site boundary limits.
How do you control pressure drop?
Baffle spacing, casing size and flow path are selected to balance acoustic attenuation with the allowable pressure drop.
Can you supply replacement silencer baffles?
Yes. Replacement baffles and acoustic panels can be engineered for existing silencers based on dimensions, duty and required performance.
